ant不能启动

本文主要是介绍ant不能启动，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

运行ant出现错误

D:\>cd ProgramFiles\apache-cxf-2.4.0\samples\java_first_pojo

D:\ProgramFiles\apache-cxf-2.4.0\samples\java_first_pojo>ant server
Buildfile: D:\ProgramFiles\apache-cxf-2.4.0\samples\java_first_pojo\build.xml
 [loadfile] Do not set property srcbuild.classpath as its length is 0.

BUILD FAILED
D:\ProgramFiles\apache-cxf-2.4.0\samples\java_first_pojo\build.xml:22: The follo
wing error occurred while executing this line:
D:\ProgramFiles\apache-cxf-2.4.0\samples\common_build.xml:75: Apache CXF require
s Java version 1.5 or higher. You are currently using Java version 1.7.

Total time: 0 seconds

将D:\ProgramFiles\apache-cxf-2.4.0\samples\common_build.xml文件中的

 <condition property="is.java.version.15">
        <or>
            <equals arg1="${ant.java.version}" arg2="1.5"/>
            <equals arg1="${ant.java.version}" arg2="1.6"/>
        </or>
    </condition>

改为

 <condition property="is.java.version.15">
        <or>
            <equals arg1="${ant.java.version}" arg2="1.7"/>
            <equals arg1="${ant.java.version}" arg2="1.6"/>
        </or>
    </condition>
